Title: Improvements in the manufacture of tubular metal bends and fittings
IPC: B21C37/29
Filed: 1952-03-03
Abstract: 765,179. Making pipe elbows, return bends, etc.; bending; stamping. HUET, A. March 3, 1952 [March 2, 1951], No. 5494/52. Classes 83 (2) and 83 (4). A localized thickening or bulge in the wall of a tube is obtained by bending the tube with localized heating in the region to be bulged or upset. In an example, in which a U-tube with a 180 degrees bend is to be made with localized thickening on the outer part of the curve, a tube a, Fig. 1, is bent by any means beyond the required 180 degrees. The outer portion c, and two inner portions AB-CD are then heated and the limbs are separated while the tube end is clamped in a die e, Fig. 2, which confines the outer radius so that the metal is upset and thickened. A straight tube may be similarly bulged by bending and subsequently straightening and larger bulges may be formed by repeating the operations. In another example in which the tube is required to be bulged the die member e, Fig. 6, has the shape of the required bulge. In other examples a U-tube which originally has a 180 degrees bend has the limbs separated in similar dies to form the bulge or thickening and the tube is subsequently restored to 180 degrees by any bending means. In a further example, the tube may be clamped in hinged dies e<SP>1</SP>, e<SP>2</SP>, Fig. 18, the shape of the dies confining the outer region of the tube so that it is upset and thickened. In other examples one or more bulges c, Fig. 17, may be formed by localized heating in the region of the required bulge. By heating one of the regions AB or CD more than the other an asymmetric bulge may be formed. The bulge may be subsequently opened out to form a pipe connection.

Title: Improvements in or relating to the preparation of melamine-formaldehyde syrups
Inventor: GRIMSHAW FRANCIS PETER
IPC: C08K3/38
Filed: 1953-02-27
Abstract: Stable aqueous or aqueous-alcoholic melamine formaldehyde syrups are prepared by adding to a solution, containing not more than 80 per cent of a condensate condensed to such a degree that it has a water tolerance between 1 : 1 and 1 : 4, an amount of 0.01-2 per cent of borax or its equivalent, e.g. boric acid or sodium metaborate and sodium hydroxide.  The melamineformaldehyde condensate is preferably prepared by refluxing the ingredients at pH 8-9.  The solution is then cooled to below 50 DEG  C. and may then be diluted with water and/or ethyl alcohol to the desired solids content, or free formaldehyde and some water may first be removed by distillation in vacuo at below 50 DEG  C.  The borax may then be added as an aqueous solution. Alternatively the borax may be added after the condensation and prior to concentration in vacuo, or as a solution in the water, alcohol or aqueous alcohol used for adjusting the solids content of the syrup.  Latent catalysts, fillers or plasticizers may be added to the syrup.

Title: Improvements in the manufacture of yarns containing staple fibre from continuous filaments
IPC: D01G1/10
Filed: 1933-05-22
Abstract: 424,879. Artificial staple fibre yarns. BRITISH CELANESE, Ltd., 22, Hanover Square, London, TAYLOR, W. I., HALE, F. C., and WOODRUFF, A. H., c/o British Celanese, Ltd., Spondon, near Derby. May 22, 1933, No. 5574/35. Divided out of 424,683. [Classes 120 (ii) and 120 (iii)] Yarn containing staple fibre is produced by causing a bundle of continuous filaments to pass between two surfaces one of which is a cutting surface moving at a speed different from that of the filaments, and the other is a stationary surface which presses the filaments against the cutting surface, whereby cutting is effected. The cutting surface is preferably the periphery of an abrasive roller, e.g. surfaced with emery or carborundum. The stationary pressing member may rest on the filaments by its own weight, or it may be pressed by spring, weight, or lever. Two stationary pressing members may be used with one cutting member. The filaments are drawn through the cutting means by a gripping roller which may be surfaced with rubber, leather or cork, together with a pressing roller which may be plain or fluted, of metal, synthetic resin, cellulose acetate or the like, or of rubber in a thin flexible metal casing; rollers having intermeshing grooves as described in Specification 410,805 may be used. The yarn may be passed more than once through the cutting apparatus. The filaments are supplied from one or more bobbins, and two or more bundles may be associated before treatment. The yarn may be wound in a cap or ring-spinning device into any shaped package for immediate subsequent use. If the yarn is to be subsequently unwound axially, it is preferably wound with a quick traverse on a bobbin having an upper flange which curves into the barrel. The yarn may be lubricated, e.g. between the gripping rollers and the collecting device, by passing it over a wick or roller, or by spraying. Filaments of different denier and characteristics may be contained in the bundle, or two or more yarns may be doubled continuously with cutting ; the cut yarn may be doubled with yarns of natural fibre ; or a light continuous thread may be fed directly to the gripping rollers and combined with the cut thread. The continuous filament yarn 1 passes between the abrasive roller 2 and a stationary member 5 suitably weighted and carried in a slotted bearing 6. The bundle is drawn over the abrasive roller by a pair of rollers 3, 4, of which the lower is fluted and the upper of rubber, the roller 4 being driven with a greater peripheral speed than the abrasive roller 2. Specifications 420,298, 424,752, and 424,830 also are referred to.

Abstract: 1,087,917. Photo-electric cells. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 11, 1965 [Feb. 14, 1964], No. 5984/65. Heading H1K. A photo-cell consists of a pressed and sintered mass of cadmium sulphide provided with electrodes and including balanced concentrations of activators and co-activators and a total of at least 10<SP>-5</SP> atoms per CdS molecule of an element or elements chosen from lead, potassium, barium, strontium, calcium and magnesium. If lead is the selected element the preferred amount is between 5 x 10<SP>-4</SP> and 10<SP>-2</SP> atoms, otherwise it is from 10<SP>-3</SP> to 10<SP>-5</SP>. Typical cells are prepared from 100 gram batches of pure cadmium sulphide to each of which quantities of nitrate solutions giving gallium and copper concentrations of 2À85 and 3 x 10<SP>-4</SP> atoms/ molecule respectively are added. Solutions of nitrates of the various additives are added to different batches to give additive concentrations of 10<SP>-4</SP> atoms/molecule, and in the case of lead between 10<SP>-4</SP> and 10<SP>-3</SP>. After mixing and prolonged drying at 120‹ C. the batches are heated at 850‹ C. for 3 hours in hydrogen sulphide and nitrogen and then ground up. Each batch is mixed with 1 gram of cadmium oxide or the equivalent amount of an oxide yielding salt, pressed into plates, and sintered at 950‹ C. in nitrogen. Interdigitated electrodes of goldindium are evaporated on each plate which is then placed in a flat silicone grease-filled glass envelope sealed off with epoxy resin. The cells switch on and off faster than cells formed without the additives but have lower sensitivity. The effects are most pronounced at high levels of illumination when lead is the additive.
